# YEN > A GPU-accelerated, terminal-first IDE for macOS with native on-device speech-to-text, 72 curated themes, built-in email/calendar, and local-first privacy — no cloud, no account required. YEN is a GPU-accelerated terminal IDE for macOS built on Metal for 60FPS+ rendering, designed around a local-first, no-cloud philosophy. It ships with native on-device speech-to-text (no AI services), a built-in file browser, Gmail and Google Calendar clients, global chat rooms, and 72 curated themes — all without requiring an account or sending data to the cloud. YEN takes a terminal-first approach to IDE workflows, adding editing and project capabilities around the terminal rather than bolting a terminal onto an editor. - **GPU Rendering** — *Built on Metal for 60FPS+ performance; no Electron, no web views, lightweight install.* - **Native Speech-to-Text** — *Hold `Option + Space` in any macOS app; audio never leaves your Mac; supports 50+ languages via macOS Speech Recognition.* - **Terminal IDE Workflows** — *`yen ide` commands cover LSP lifecycle, project search, PR review, devcontainer control, encrypted terminal sharing, verification gates, and agent adapter orchestration.* - **72 Curated Themes** — *Live preview and instant apply via `Cmd + ,`; comfort settings (font, cursor, opacity, padding) stay independent of theme switches.* - **Built-in Bundled Tools** — *Ships with fd, rg, fzf, zoxide, bat, jq, btop, fastfetch, and lazygit — zero Homebrew setup required.* - **File Browser** — *Terminal-native browser (`Cmd + Shift + O`) with syntax-highlighted previews, fuzzy find, git status indicators, and cd-on-quit.* - **Email & Calendar** — *Built-in Gmail client and Google Calendar TUI accessible via `mail` and `calendar` commands.* - **Global Chat** — *Built-in chat rooms (Lounge, Feedback, Show & Tell, Support) via the `chat` command.* - **Split Layouts & Tab Sidebar** — *10 one-click split presets, persistent or transient tab rail, custom split pane labels, and full window state restoration.* - **Local-First Privacy** — *No required desktop account, no desktop telemetry, no AI watching your commands; website uses only anonymous aggregate analytics.* To get started: download the DMG from yen.chat, drag YEN to Applications, right-click and select Open to bypass Gatekeeper, then run `yen init zsh` (or bash) in external shells to enable shell integration. ## Features - GPU-accelerated terminal rendering via Metal at 60FPS+ - Native on-device speech-to-text (Option + Space, 50+ languages, no cloud) - Terminal-first IDE with yen ide workflow commands - 72 curated bundled themes with live preview - Built-in file browser with syntax-highlighted previews and cd-on-quit - Bundled tools: fd, rg, fzf, zoxide, bat, jq, btop, fastfetch, lazygit - Built-in Gmail client (compose, reply, forward, labels, search) - Built-in Google Calendar TUI (agenda, month, day, week views) - Global chat rooms (Lounge, Feedback, Show & Tell, Support) - Split pane layouts with 10 one-click presets - Tab sidebar (transient or persistent docked rail) - Quick Terminal global hotkey dropdown (Ctrl + `) - Scratchpad panel (Cmd + Shift + J) - Command palette (Cmd + Shift + P) - LSP lifecycle management and diagnostics - Encrypted terminal sharing with expiry and revoke - PR review workspace with inline comments - Devcontainer and VS Code inventory/import - Shell integration for bash, zsh, fish, elvish, nushell - Window state restoration across splits, tabs, and positions - Local weather via Open-Meteo with ASCII icons - Custom keybindings with conflict detection - Settings export/import - No account required, no desktop telemetry, local-first ## Integrations Gmail, Google Calendar, GitHub (PR review, notifications), Claude (agent adapter), Codex (agent adapter), VS Code (inventory/import), devcontainer, upterm, tmate, Open-Meteo, Sparkle (auto-updates), macOS Speech Recognition, macOS SpeechAnalyzer / DictationTranscriber ## Platforms WINDOWS, MACOS, LINUX, WEB, API, VSC_EXTENSION, CLI ## Pricing Free ## Version 0.999 ## Links - Website: https://yen.chat - Documentation: https://yen.chat/docs - EveryDev.ai: https://www.everydev.ai/tools/yen-terminal
